Question

The diagonals of three faces of a cuboid is 13 root 281 and 20 then the total surface area

Answer 1

Answer:

20 means 5x4

Let's assume 2 sides are 3x4 and 4x4 ie. 12 16 are 2 dimensions. . Since another diagonal is

13 it means a 5 and 12 are 2 dimensions.. Therefore total surface area is 2(lb +bh +lh)
